business cards in pages

If you are using a template (in Pages) for designing a business card, you start with "editing" your own information onto ONE of the cards, then you should be able to apply those changes (of your personal information & photo) to all the other cards. So far, I haven't been able to figure out how to do that, as it is not self-evident, and there are no sections of the Pages help info to explain how to do such a simple and typical edit. It would be very tedious to have to edit each and every card separately, instead of just being able to do it once and then apply that design to all the cards on the page. Help please!
